Grapevine named ‘SV22-104e-84’

ABSTRACT

A new and distinct variety of grapevine plant named ‘SV22-104e-84’ particularly characterized by its green berry color, very firm texture and very large, sweet berries. Additionally, berries of the new cultivar are very responsive to applications of exogenous gibberellic acid, doubling in size in comparison to untreated fruit.

STATEMENT OF ANY FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

The present invention is not subject of Federally-sponsored research or development.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of grapevine botanically known as Vitis vinifera and hereinafter referred to as grapevine named ‘SV22-104e-84’. As used herein, ‘grapevine’ refers to all plant parts including, vines, canes, tendrils, leaves, fruit and roots of ‘SV22-104e-84’. Grapevine named ‘SV22-104e-84’ is the result of an effort to produce a late ripening, green, seedless table grape with fruit characteristics superior to currently available green grape cultivar ‘Thompson Seedless’ (unpatented) and ‘Autumn King’ (U.S. Plant Pat. No. 16,284). This new cultivar originated from a cross conducted in May 2001 near McFarland, Calif. between pistillate grapevine plant selection ‘13-2-138’ (unpatented) and pollen parent ‘Princess’ (unpatented). Resultant ovules from the cross were harvested 42 days after pollination and cultured on agar substrate containing ‘McCown's Woody Plant Medium’. Embryonic plants were dissected from those cultured ovules after twelve weeks and were transferred to culture tubes containing the same medium in the laboratory under twelve hours of light from standard fluorescent lamps at 27° C. The seedlings from this effort were transplanted to the greenhouse in November of 2001 and grown in the greenhouse at 29° C. with 12 hours illumination under high pressure sodium vapor lamps. The seedling population of 127 plants was planted in the field in the spring of 2002 near Delano, Calif. The new grapevine was selected from this seedling population on Oct. 6, 2006. It was then propagated by cuttings and grafted to ‘Freedom’ (unpatented) rootstock in 2007. The present invention has been found to retain its distinctive characteristics through four successive asexual propagations.

Grapevine named ‘SV22-104e-84’ differs from the female parent grapevine ‘SV13-2-138’ (unpatented) in that ‘SV22-104e-84’ has ellipsoidal shaped, seedless berries and flowers with functional pollen, whereas ‘SV13-2-138’ has spherical shaped berries with partially lignified seed traces and flowers that are pistillate (functionally female).

Grapevine named ‘SV22-104e-84’ differs from its male parent, ‘Princess’ (unpatented) in that ‘SV22-104e-84’ has ellipsoidal shaped, bright green berries that do not brown internally while in cold storage, whereas ‘Princess’ has oblong shaped, yellow berries which may brown internally while in cold storage.

Grapevine named ‘SV22-104e-84’ differs from the commercial cultivar ‘Thompson Seedless’ in that ‘SV22-104e-84’ has ellipsoidal shaped, bright green berries, whereas ‘Thompson Seedless’ has elongate shaped, light green berries. The berries of ‘SV22-104e-84’ have a superior eating quality and larger berries at harvest after standard vineyard practices of application of exogenous gibberellic acid and girdling of the vine trunks as compared to ‘Thompson Seedless’. Additionally, ‘SV22-104e-84’ has fruitful shoots with spur pruning to two buds, whereas ‘Thompson Seedless’ lacks fruitfulness with spur pruning. ‘SV22-104e-84’ is most similar to its sibling grapevine named ‘SV21-66-158’ (U.S. Plant Pat. No. 24,510), from which it can be distinguished by lower fruitfulness (1 cluster on most shoots versus 2 clusters on most shoots of ‘SV21-66-158’), higher plant vigor and later ripening.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices near McFarland, Calif.:

-   -   1. Green skinned;     -   2. Very firm berry texture; and     -   3. Very large, ellipsoidal shaped berries with sweet taste.

BRIEF DESCRIPTION OF THE DRAWINGS

This new grapevine is illustrated by the accompanying photographs which show fruit clusters, leaves, canes, and tendrils. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from a plant about 8 years-old, grown in a field near McFarland, Calif. in 2015.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following detailed description sets forth the distinctive characteristics of ‘SV22-104e-84’. Descriptions of the new invention apply to vines of ‘SV22-104e-84’ grown on ‘Freedom’ rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2015. These vines were in their eighth year of full production having been grafted to existing rootstock ‘Freedom’ in 2007. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. Color references are primarily to The Royal Horticultural Society's Colour Chart, The Royal Horticultural Society, London, United Kingdom. Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV) and published in Descriptors for Grapevine (Vitis spp.) (Anonymous, International Plant Genetic Resources Institute, 1997, ISBN 92-9043-352-3).
